IMPROVEMENI IN SIZING'AND FlNlfSHING COVERED SKIRT-WIRE.l

Specilcation forming part of Letters Patent No. 48,765. dated July 11, 1865.

To all whom it mag/concern:

Be it known that I, W. E. FROST, of Worcester, of Worcester county, in the State ofMassa chusetts, have invented. certain new and useful Improvements in Machinery for Sizing and Finishing Covered Skirt-Wire; and Ido here-- by declare that the following is a i'ull and exact description thereof', reference being had 4to the accompanying drawings, making part of this application.

Myinvention relates to certain improvements in machinery for sizing and finishing braided or covered skirt-wire or other similar articles or material.

Previous to my present invention it has been customary to perform the operations ot' sizing and finishing upon braided wire by passing-it through a starch bath, and thence back and forth arouild or over heated rolls, as, for instance, in the manner set forth and described in an application for other Letters Patent by me.

It is sometimes desirable to put a considerable gloss or polish on the finished article or fabric, and I have discovered that by first pass- 'ing the material, while the coating of size is yet wet, in contact with smooth hot surfaces, or against rapidly-revolving surfaces moving in an opposite direction to that in which the wire is moving, so as to createfriction and heat, and then over the cylinders, a fine gloss may be produced. 1

My present invention consists in passing the wire or other equivalent material through'a Vsize or starch mixture, thence between and in contact with ironers or polishers, from whence it passes over the drying-rolls, as will be hereinafter more fully described i -To enable those skilled in the art to make and use my invention, I will proceed to describe the same, referring. by letters to the ac- K companying drawings, in which- Figure 1 is a top view ot' my improved machine or apparatus. Fig. 2 is a vertical section at the line a: a', Fig. 1;

In the several figures the same part is indicated by the 'same letter ot' reference.

A is'the base or iloor upon which thc work- In a suitable frame-work, B, are hung two metallic hollow rolls, C D, which I propose to make of copper, which turn freely upon their axes.

Nearone ot' these rolls, C, are arranged, supported by said frame-work, two semi-cylinders, E F, which are hollow, and supplied with steam oir other heating medium, and which serve as polishers or ironers, aswill be"presently explained, and beyond these polishers is arranged the starch bath or vat a and its-rollers b c, and beyond this again is hung the reel Gr, from which the wire is supported to the machine. H i's another reel at the other end' of the framework, which is rotated by any suitable means, and draws oft' the finished wire. The wire to be sized and 'finished is passed from' a reel or coil at G through or between the sizing-rolls b c, Where it is coated with the starch mixture,

Aand thence between the convex surfaces of the polishers E F, and thcncmback and forth over the rolls C D, (crossing each time,) and thence Oli' onto the reel H, as clearly illustrated at l, 2, 3,- &c. By passing the coated wire directly from the size bath, or whereit is coated, to the polishers, as described, the ironing-surfaces ot the said polishers are broughtin contact with both the moist sized surfaces of the wire, and

the" said surfaces are drawn alongin such coi1.

tact, whereby a finer gloss is imparted to the surface of the material than it would receive by merely passing over thc'rolls and being dried.

K are heater-pipes, which are arranged below the drums, over-'which the wire passes back and forth, and which, being heated by steam or otherwise, serve to dry the coated wire as it passes back and forth over the rolls.

' The polishers E F should be set so that a horizontal plane tangential to the convex slurfa-ce of the lower one will be a little above a l similar plane touching the surfaces of the upper ironer.' By thus arranging the polishers it will be seen that considerable friction will be created between the said polishers and the Vmaterial as the latter passes between them,

glossed.

In lien of the hollow steam-heated polishers E F, as shown, two series of smooth steampipe; arranged each in the arc of a ,circlc, may be used witnbut departing from the spirit ot' my invention; or, in place ofthe said polishers, two revolving shafts may be employed, turned smooth on their surfaces and rotated in a diwhereby the surfaces (both oi' them) will be 'rection opposite to that in whichl the wire isl fed along. I havefound that small revolving shafts thus arranged will create heat and frio- .tion-sufcient to beautifully gloss the surface of theqyire.

The number of ironers or polishers may be varied, of course, without departing from my invention. l l

The only Qbject and advantage of passing .the sized and i-roned `wire over the rolls C D and nearvthe steam-pipes K are to thoroughly' dry the wire before it is rereeled, otherwise it y will b e aptto corrode.

Bars u o maybe s o arranged with guidepinsppa's to keep the strands'in their proper relative positions.

Whereitisidesired to puta line gloss' on the material it may be expedient to put a proper amount of sperniaceti in the starch ory size.

Having fully described my improvement,

what I claim as new, and desire to secure by Letters Patent, is.- y

Passing the'wire through the starch or size, and thence directly in contact with ironers or polishing-surfaces, substantially as described,
